Costa Coffee - Mince Tart

In the town where I work, there are 3 Costa coffee stores. All within a 2 minute walk from each other. Most recently, there has been a Costa Coffee stall that has appeared, again, well within a 2 minute walk from each others. So, when I decided to start reviewing coffee shop mince pies, Costa had to be the first choice because they were everywhere I turned. Lets see how their mince pie tart does this year.
